Letters Patent No. 111,973, dated February 21, 1871.

IMPROVEMENT 1N MACHINES FOR BRNZING.

The Schedule referred to in these Letters Patent and making part of the same.

v.To all whom it may concern.'

Bel it known that I, ISRAEL L. G. Rien, of Gambridge, in the county of Middlesex and State of Massachusetts, haveinvented a certain new and useful Improvementiu Brewing-Machines; and I do hereby declare the following to` be a full, clear, and exact description thereof, reference being had to the accompanying drawings forming a part thereof, and in which, by the several iignres indicated thereon under their proper headings, is illustrated my invention.

'lhis invention relates to bronzing-rnachines in which the paper orarticlc to be bronzed is passed between two series of rollers covered with velvet or other suitable material or covering, to receive and retain the bronZing-powder, supplied to them from-a suitablylocated reservoir and lspout dependent from the latter, t-hepowder or bronze being equally distributed upon the entire surfaces or peripheries of the said rollers with which the bronze is applied to the article to be bronzed, by means of a reciprocating brush, and in which is employed a casing of peculiar construction yfor enveloping a portion ot' the above-described devices, as hereinafter set forth.

Similar letters ot' reference in the several figures of the accompanying drawings indicate corresponding parts of my invention.

In the said drawings.-

A represents a block or casing, having cut transversely through it a series of cylindrical holes or chambers, within which are located the bronzirig-rollers B B and dusting or cleaning-brushesG C, and extending through its entirelength, and nearly its whole width, a receptacle, b, of sufficient size to allow the paper or article to be bipnzed to pass through it while being operated upon. I

At the point where the article or matter is introduced into the chamber or receptacle b for bronzing is cut a month, a, made as seen in transverse section of block A, for facilitating the introduction of the said matter in said chamber.

The lower portion ot block A is constructed or formed with a leaf, a, the upper surface of which is slightly inclined and forms a continuation of the lower surface or bottom of chamber b. Uponthis leaf the matter to be gilded or bronzcd is placed preparatory to being introduced into b of block A. The block A and the outer end of leaf ibrining a part of the. same, are supported upon legs or uprights suitably secured thereto, the snpports'or legs of the block A -heingheld together-'by the transverse pieces u 11.', in which .the shaft I has its bearings.

The bronzing-rollers, or the ones between which the mattei' to be bronzed is inserted, are covered with velvet or any other material having sutiicient elasticity to yield to diiereut thicknesses ot' paper or tho. matter to be operated upon, and are composed of au upper and a lower set of rollers supplied with shafts, the shafts of the lower set consisting of cylindrical shoulders or projections formed ou the ends thereof and having their bearin gs in apertures cut in the side pieces V V', nailed or otherwise secured to the sides ofthe block A, the said shoulders having been allowed to first pass through apertures cut in the said block before entering the holes or bearings in the pieces V V'.

The shafts ot the upper set of the brouzing-rollers have one end enteringr apertures in the side pieces or supports V V, and the other end .extending through the block A and bearings or suppo1'ts,\j"\,a suitable distance therefrom, where they are supported and have their bearings upon a cross-piece., Z, secured to the upper end ofa pair otlegs.

N is a reservoir or receptacle containing the bronze, located upon the block A and having an aperture or spout leading from it to the chamber of one ot' the bronZing-rollers, through which the bronze is fed to the said rollers.

` E is a brush, having the lower side of its top resting iiush with the upper side or top of the block, and the bristles or hair portion thereof entering an opening in the block and coming in contact -with the peripherics of the upper rollers B B, upon which the bronze is poured.

A reciprocating mot-ion is imparted to this brush through the connecting-rod F, pivoted at 011e end to its center and at the other end supplied with an aperture of an eccentricl shape, into which works a pin or headed projection formed ou the right-angular shaft G, having its bearings in pieces secured to the block A, and operated by means ot' the driving-shaft I through the bevel-gearing H H, attached respectively to thc shaft G and shaft I and handle M on the shaft last named.

'lhe object of giving a reciprocating motion to the brush E, constructed as plainly shown in a detached view in the drawing, is to 'cause it to come in contact with the entire surface of the pcripheries oi' the bronzing-rollers while being revolved, in order to equally distribute the bronzing-powder upon said rollers with which said powder is applied to the article to be bronzed.

The revolving brushes C C, placed one above the other, are located upon shafts similar tothe rollershuits-B l5, and are for the purpose ot removing subetween the rollers B B.

D Dare the delivery-rollers, covered with cloth or rubber and arranged in'relation to one another similar to the rollers B B, and upon shafts similar to those of the rollcrsj ust mentioned, but having their bearings in jaws or projections formed on the outside of block A, and not inside ofthe Said block. These rollers seize perliuous bronze from the article after having passed the article that has been bronzed, after having been cleaned or dusted by the brushes C C, and carry it out of the block A at the point marked by the letters l1 l).

Motion is imparted to the rollers B B, brushes C C, and rollers D D by means of the belts L L, which pass around and receive motion from the pulleys J J 2 J 3 J" J5, located upon the shaft I, and thence around pulleys Kl K2 K3 K K, situated upon the shafts of the said rollers and brushes.

The motion imparted to the dusting-brushes C G is contrary to that of the rollers B B, their belts being twisted or arranged in such a manner as to obtain said motion for the purpose of, throwing the superfluous bronze back onto the bronzing-rollers B B, removed from the article after having been bronzed, thereby economizing in the use ofthe broming-powder, which is very costly.

a yIt will be remarked that, in order to cause the rollers D D to seize the' papel' upon its margins as it leaves the dusting-brushes C O, so as to avoid defacing or disfiguring the printed portion thereof', their shafts are supplied with collars or washers of less diameters than themselves, (the rollers,) located upon the shafts between the rollers, keeping the latter the required ds' tance apart. The rollersand their collars are both removable and can be keyed to their shafts by means of the ordinary key used for that purpose, when it is desired they should revolve with their shafts.

Having thus described my invention,

1'. The table or block A, constructed with the leaf a, chamber or receptacle b et", chambers for the reception of the rollers B B and cleaning-brushes C C, ap-

rollers, and receptacle for the brush E, substantially as and for the purpose set forth.

2. The velvet or other suitably-covered bronzingrollers B B, in combination with the receptacle or reservoir N, with its spout and reciprocating brush E, for equalizing the distribution of the bronze upon said rollers B B, all constructed and arranged substantially as set forth, v

3. The casing or block A, constructed as described, in combination with the brush E, receptacle N, rollers B and D, revolving brushes C C, shafts Gr and I,

stantially as and for the purpose set forth.
